Tried updating BIOS and no improvement New SATA Cable didn't do it. I also fitted a new CPU (Intel Core2Duo E5600) and problem still exists. IE8 stops responding, updates fail or get half way through and stop, Windows explorer stops working then different BSOD every time. I have replaced everything now apart from the Motherboard and PSU so new PSU and mainboard next i think. Will have to get a new case to fit it all in as the current one only fits the HP motherboard which is Micro ITX and you can't buy replacements anywhere.Edited by Darylrese - 7/19/11 at 2:04pm
